- The ports of Long Beach and Los Angeles are responsible for roughly 50% of all emissions in the LA metro area—equivalent to 6,000,000 cars
- The port of Rotterdam generates more emissions than three coal-fired power plants on a yearly basis
- The shipping industry will be responsible for 17% of total global emissions by 2050 if nothing is done to decarbonize on a large scale
There, are, however opportunities that fleet owners can begin to look at. Emerging high-performance, low-cost, inherently non-flammable chemistries (such as the ones being developed by Alsym Energy) are ideal for maritime applications and can be used in ways that help to lower emissions significantly in the next five to ten years. Here are three of them:
- Portside operations: Some ports have started to provide electrical hookups that ships can use while docked, making the use of auxiliary diesel generators unnecessary. When docking at ports that haven’t installed these connections yet, onboard batteries could power systems such as HVAC, communications, navigation and more.
- Arrivals and departures from ports: Many ports have begun requiring ships to switch from high-sulfur heavy fuel oil (HFO) to more expensive low-sulfur formulations within twenty miles of shore, as well as observe strict speed limits to minimize GHG emissions. Battery arrays can be installed that ships could use for low-speed propulsion as they enter and leave port, with primary engines shut down completely.
- Peak shaving: It’s common for ships at sea to need more power than can be provided from one engine, but not the full power of two. In these situations multiple engines run at sub-peak performance, creating more pollution and reducing fuel efficiency. Instead, on-board batteries could be used to provide fractional engine power, allowing one engine to run at peak efficiency and shutting any others down completely.
Starting with our first year of commercial production, we’ll supply the two companies with 1 GWh of battery systems per year–roughly enough for 100 ships–to support the applications listed above. By using low-cost, inherently non-flammable raw materials with robust global supply chains, we aim to provide batteries at a fraction of the cost of lithium-based technologies, making electrification both safe and economically viable. These batteries can help reduce risks to crew and cargo, as well as lower insurance costs for fleet managers and shippers.
“Zero-emission vessels are the future of maritime shipping, and we’re working with like-minded owners, including Nissen Kaiun, to decarbonize every part of the ecosystem as quickly as possible. By lowering the cost of electrification and minimizing the risk of battery-related fire events, Alsym’s technology is well-placed to be a safer alternative that can help the shipping industry meet its goal of zero net emissions by 2050—especially in light of the European Commission’s recent proposal to classify lithium as toxic.”– Captain Rajesh Unni, Founder and CEO of Synergy Marine Group
